Uses of R Injection
Benefits of R Injection
In Hormone replacement therapy
Hormone placement therapy (HRT) is a treatment to relieve symptoms of menopause such as hot flushes, night sweats, mood swings, vaginal dryness, and reduced sex drive. Since menopause can last for several years, this treatment can make a big improvement to your daily life and mood. Progesterone is one of two important hormones (the other being is estrogen) used in this treatment. However, it may not treat all your symptoms, consult with your doctor. You should use this medicine as it is prescribed, and for as long as it is prescribed by your doctor.
In Treatment of Female infertility
R Injection contains progesterone, a female hormone that is important in the regulation of ovulation and menstruation. It is used to cause menstrual periods in women who have not reached menopause but are not having periods due to a lack of natural progesterone in the body.
